Making precise wall and coating thickness measurements can be fast and easy using the TI-CMX, TI-CMXDL (data-logging) and TI-CMXDLP (data-logging & A-scan) ultrasonic thickness gauges. Not only do the models measure coating and wall thickness quickly and accuratelyâ€”from only onesideâ€” but they automatically measure and eliminate any coating from wall thickness measurements, allowing users to locate the finest corrosion and pittingâ€”without removing the coating. Four user-selected operating modes are included: Coating On, Coating Off, Thru Coat and Coating Only. All measurements are temperature compensated. An oversized backlit graphic LCD features easy-to-read fonts, graphics and display codes switch show all critical settings. The units add built-in memory with RS-232 output for transferring data to a Printer or PC. It also includes free Datacomm Data Transfer & Analysis Software and an RS-232 cable. Data Files can be user-set for a ''grid type'' structure or a ''sequential'' file.
